IMPROVEMENT IN MECHANISMS FOR UNLOADING HAY.

Specification forming part of Letters Patent No. 168,330, dated October5, 1875; application filed September 9, 1875.

To all whom it may concern:

Be it known that I, WARREN H. HAYNES, of North Sudbury, of the county ofMiddle sex and State of Massachusetts, have invented a new and usefulMechanism for Unloading Hay into a Barn and do hereby declare the sameto be fully described in the following specification and represented inthe accompanying drawings, of which- Figure 1 is a top View, Fig.2 aside elevation, Fig; 3 a longitudinal section and Fig. 4 a transversesection, of the frame of a barn with my hay-unloader and its cartarranged therein.

In such drawings, the said frame is shown at A, and the hay-cart at B.With such cart there is used a platform, 0, which, while restingdirectly upon the cart-body, and the latter is in the field, is to havethe hay piled or stacked upon it, after which the cart, laden with thehay, is to be drawn from the field into the barn and upon the floorthereof. At its four corners the platform 0 is provided with eycbolts aa a a, to each of which there is fixed a chain, b, furnished at its freeend with a hook, 0. Four hoistingropes, d at d d, supplied with hooks ee cc to hook into the eyes of the said eyebolts, lead upward to andthrough four blocks or pulleys, f f f f, sus

- pended from the rafters of the frame A near vertical posts 9 g g 9,arranged in manner represented, and making part of the said frame. Eachof the said posts is provided with a series of hooks or staples, h h,&c., disposed in it as shown.

Furthermore, directly below the several pulleys f f f f there are fixedin standards erected in the barn-floor 2' four leading sheaves orpulleys, k 70 k 70, around which the four ropes are passed, in manner asrepresented. A pair of said ropes on one side of the cart is secured toone of two chains, 1 m, the opposite pair of ropes being fixed to theother chain. These chains are hitched on studs 11. 0, extending up fromthe frame 1) of a capstan, D, arranged as represented. To the barrel uof the capstan there is fixed a rope, q, terminating in two chains orbranch ropes, r 8, provided at their free ends with hooks t t.

With the above-described mechanism a load of hay may be raised to anydesirable elevation in the barn and dumped toward either side or endthereof. To accomplish the raising of a load from the cart and thedischarging of said load upon the spot or place for its reception, aperson should proceed as follows-that is to say, he should hook theraising-ropes into the eyebolts of the platform, and also should hookthe chains r 8 into the chains Z m, after which he should revolve thecapstan D, whereby all the raising-ropes will be simultaneously pulledupon. Having raised the platform to the required elevation, he is nextto raise it at one side or one end only, so as to cause it to dischargeor dump its load. This he can do by hitching the chains Zm upon thestuds n 0, and next unlocking one of the chains 1" s from its chain l orm, and again turning the capstan, so as to draw only upon the ropes thatmay be necessary to eflect the tipping of the platform or raising it upinto a vertical position. The chains b b of that side or end of theplatform which is not to be raised may first be hooked into staples ofthe posts.

With mechanism as above described applied to a barn and a hay-cart, aload from the latter may be raised to any desirable elevation within thebuilding, and subsequently be cast off or dumped,-all being accomplishedin a very short period of time, and with little labor in comparison towhat would be required to efi'ect such by pitchforks in the hands of oneor more persons.

Instead of the branch chains 1 s to the capstan-rope I sometimes apply apulley to it, and connect together the chains Z on of the raisingropesd, so as to make one chain thereof to go through said pulley.

By hooking the leading-ropes on one side of the platform to hooks in theposts the included side of the platform, when drawn up to the hooks,will stop, the other side continuing to be drawn up so as to tip theplatform.

I claim as my invention as follows, viz:

1. The combination of the leading-chains l m and the branch chains 1 8,provided with hooks H, as described, with the capstan D, its h, arrangedin each, as and for operation with studs 4% 0, rope q, and the fourleading-ropes d a platform, its hooked chains, and elevating d d d, andtheir gnide-pulleys f is, applied to mechanism as explained. thebarn-frame A, and for use with a platform, WARREN H. HAYNES. 0, all asrepresented. Witnesses:

2. The barn-frame A, provided with the R. H. EDDY, four posts 9 and aseries of hooks or staples, S. N. PIPER.
